Understanding Prediction Markets: Prediction markets, like Polymarket, allow users to bet on the outcome of future events. The probability displayed for a market is determined by the trading activity of users. If a particular outcome is perceived as more likely, its probability will rise as users buy shares representing that outcome. Conversely, if an outcome is seen as less likely, its probability will fall. The probability is calculated as the total value of shares representing a specific outcome divided by the total value of all shares in the market. A probability of 99.95% suggests that the market overwhelmingly favors one specific result (either Over or Under 217.5 points) based on current trading and information.
